Connecting the Input Source
Use a HDMI cable to connect the input source to the female HDMI socket on the rear panel
(
b
in gure 2).
The connectors are fully HDCP compliant. With cables up to 25 feet (7.6 m) they support
resolutions of up to 1080p @ 60 Hz with 12-bit color. With cables up to 50 feet (15.2 m) they
support 1080p or 1920x1200 @ 60 Hz with 8-bit color.
Follow these instructions to secure the input and output
HDMI connectors to the HDMI DA2 with the LockIt
™
HDMI lacing bracket provided:
1. Plug the HDMI cable into the panel connection.
2. Loosen the HDMI connection mounting screw from
the panel enough to allow the LockIt lacing bracket
to be placed over it. The screw does not have to be
removed.
3. Place the LockIt lacing bracket on the screw and
against the HDMI connector, then tighten the screw
to secure the bracket.
ATTENTION: Do not overtighten the HDMI
connection mounting screw. The
shield it fastens to is very thin
and can easily be stripped.
4. Loosely place the included tie wrap around the HDMI
connector and the LockIt lacing bracket as shown.
5. While holding the connector securely against the lacing bracket, tighten the tie wrap, then
remove any excess length.
Connecting the Output Displays
Use a HDMI cable to connect up to two output displays to the female HDMI sockets on the rear
panel (
c
in figure 2 on page 3).
NOTE: Secure the input and output HDMI connectors to the HDMI DA2 with the provided
LockIt
™
HDMI lacing bracket (see Connecting the Input Source).
Connect the primary display to output 1 since EDID from output 1 is read and stored
automatically. If necessary, EDID can be congured using SIS commands (see page 17).
The HDMI DA2 monitors the EDID of each connected display to ensure it is compatible with the
current input signal. The following adjustments are made for each output independently:
z Interface format: If the connected display is DVI and the input signal is HDMI, the signal
is reformatted to DVI. If the output is HDMI and the input is DVI, no reformatting is needed
because HDMI is backwards compatible with DVI.
z Video color bit depth: If the connected output device does not support the color
bit depth of the input signal, it is truncated down to the next level that is supported
(12-bit > 10-bit > 8-bit). The signal can be forced to always truncate to 8-bit via SIS
commands, disabling deep color.
z Audio: If the connected output device does not support the audio format of the input
signal, audio is muted.
If the source requires HDCP encryption and the display is not HDCP compliant, that output
channel outputs a green screen.
Both outputs carry +5 VDC and up to 250 mA on pin 18, regulated by a current limiting circuit.
